The Rox 01 1.5T 56.01 kWh (476 Hp) Range Extender 4WD is a plug-in hybrid electric vehicle (PHEV) SUV produced by Rox, entering production in August 2023. Positioned as a flagship model within the Rox lineup, it represents the brand’s entry into the competitive mid-size SUV segment, specifically targeting consumers seeking a blend of electric efficiency and extended range capability. The 01 is notable for its unique powertrain configuration, utilizing a 1.5-liter turbocharged engine solely to power a generator, which in turn charges the battery and powers two electric motors – one driving the front wheels and another driving the rear wheels, resulting in all-wheel drive. The vehicle is designed to accommodate between six and seven passengers, offering a spacious interior and a focus on modern technology.

Powertrain & Engine Architecture
The Rox 01’s powertrain is its defining feature. It employs a 1.5-liter turbocharged inline-four cylinder engine (code B15F) producing 156 horsepower. However, this engine doesn’t directly drive the wheels. Instead, it functions as a range extender, powering an electric generator. The generator then provides electricity to the two electric motors – a 204 hp motor driving the front wheels and a 272 hp motor powering the rear axle. This configuration results in a combined system output of 476 horsepower and 740 Nm (545.8 lb-ft) of torque. The engine utilizes direct fuel injection and an intercooled turbocharger to maximize efficiency and power output. The single-speed automatic transmission is integrated with the electric motors, providing seamless power delivery. The 56.01 kWh lithium-nickel-manganese-cobalt oxide (Li-NMC) battery pack, located under the floor, provides an all-electric range of 235 km (146.02 miles) according to WLTC standards.
Driving Characteristics
The Rox 01 delivers a unique driving experience due to its range-extender setup. In pure electric mode, the vehicle offers quiet and smooth acceleration. When the battery is depleted or requires additional power, the 1.5-liter engine seamlessly kicks in to generate electricity, maintaining drive power without noticeable interruption. The combined output of the electric motors provides brisk acceleration, achieving 0-60 mph in approximately 5.2 seconds. Compared to potential future variants with larger batteries or more powerful engines, this configuration prioritizes a balance between electric range and overall vehicle weight. The all-wheel-drive system provides enhanced traction and stability in various driving conditions. The single-speed transmission offers simplicity, but lacks the gear ratios found in traditional automatic transmissions, potentially impacting efficiency at higher speeds.
Equipment & Trim Levels
Specific trim levels and standard equipment for the Rox 01 1.5T 56.01 kWh variant are currently limited in publicly available information. However, given its positioning as a flagship model, it is expected to include a comprehensive suite of features. These likely include a large touchscreen infotainment system, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane-keeping assist, premium interior upholstery, and a panoramic sunroof. Optional extras may include upgraded sound systems, ventilated seats, and advanced parking assistance features. The spacious interior is designed to comfortably accommodate six or seven passengers, with flexible seating configurations.
Chassis & Braking
The Rox 01 utilizes a double wishbone suspension setup at the front and an independent multi-link suspension at the rear, designed to provide a comfortable ride and responsive handling. Ventilated disc brakes are employed on all four wheels, ensuring adequate stopping power. An anti-lock braking system (ABS) is standard. The vehicle’s relatively high curb weight of 2735 kg (6029.64 lbs) necessitates a robust suspension and braking system. The electric steering system provides precise and responsive steering feel. The 21-inch wheels, fitted with 275/45 R21 tires, contribute to both the vehicle’s aesthetic appeal and its grip levels.
Market Reception & Comparison
As a relatively new entrant to the market, detailed market reception data for the Rox 01 1.5T 56.01 kWh is still emerging. However, the vehicle’s unique range-extender powertrain and spacious interior are expected to appeal to consumers seeking a practical and efficient SUV. Compared to other PHEV SUVs in the market, the Rox 01 differentiates itself with its dedicated range-extender approach, rather than relying on the engine to directly drive the wheels. Fuel economy and long-term reliability data are yet to be fully established, but the use of established battery technology and a well-engineered powertrain suggests a promising outlook.
Legacy
The Rox 01 1.5T 56.01 kWh represents a significant step for Rox as a brand, showcasing its commitment to electric mobility and innovative powertrain solutions. The long-term reliability of the powertrain will be a key factor in establishing the vehicle’s reputation in the used car market. The unique range-extender configuration may prove to be a valuable asset, offering a compelling alternative to traditional battery-electric vehicles for consumers concerned about range anxiety. The vehicle’s success will likely influence Rox’s future product development and its overall strategy in the rapidly evolving automotive landscape.
